Abstract
Reactive spark plasma sintering (RSPS) is used to obtain single-phase samples of medium-entropy BiSbTe1.5Se1.5 compounds (low-temperature thermoelectric electronic type of conductivity) and PbSnTeSe (medium temperature hole-type thermoelectric conductor) from a mixture of powders of the corresponding elemental metals. The obtained samples are polycrystalline with lamellar grains with the average size of ~3.3 µm in BiSbTe1.5Se1.5 and with irregularly shaped grains with the average size of ~18.9 μm in PbSnTeSe. The maximum thermoelectric figure-of-merit of the samples is ~0.43 (at 500 K for BiSbTe1.5Se1.5) and ~0.35 (at 725 K for PbSnTeSe).
